  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Percent identity by BLAST analysis: Human, Gorilla, Gibbon, Monkey, Marmoset, Mouse, Rat, Hamster, Elephant, Panda, Dog, Bat, Bovine, Horse, Rabbit, Opossum (100%); Turkey, Chicken, Platypus, Lizard, Xenopus, Stickleback, Pufferfish, Zebrafish (93%).
LS-E26212 - Lyophilized - 100 µg - $145.00
Human PIK3CA.
Immunohistochemistry: LS-B2451 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-B2451 was determined to be 2.5-5 ug/ml.


Tris-buffered saline, pH 7.3, 0.5% BSA, 0.02% sodium azide

About PIK3CA / PI3K Alpha

P42336 NM_006218 NP_006209.2

PIK3CA Antibody, MCAP Antibody, p110-alpha Antibody, p110alpha Antibody, PI3K Antibody, PI3-kinase p110 subunit alpha Antibody, PI3-kinase subunit alpha Antibody, PI3Kalpha Antibody, MCM Antibody, MCMTC Antibody, PI3K-alpha Antibody, PtdIns-3-kinase subunit alpha Antibody, CLOVE Antibody

Phosphoinositide-3-kinase (PI3K) that phosphorylates PtdIns (Phosphatidylinositol), PtdIns4P (Phosphatidylinositol 4-phosphate) and PtdIns(4,5)P2 (Phosphatidylinositol 4,5-bisphosphate) to generate phosphatidylinositol 3,4,5-trisphosphate (PIP3). PIP3 plays a key role by recruiting PH domain-containing proteins to the membrane, including AKT1 and PDPK1, activating signaling cascades involved in cell growth, survival, proliferation, motility and morphology.


Anti-PIK3CA antibody IHC of human heart. Immunohistochemistry of formalin-fixed, paraffin-embedded tissue after heat-induced antigen retrieval. Antibody LS-B2451 concentration 5 ug/ml.
